TIPPING-MACHINE.

To all whom it concern i Be it known that L'GEORGEiA. MARSH, ofDixfield, in the'county of Oxford and State of Maine, have inventedcertain new and useful Improvements in Tipping-Machines, of which thefollowing is a specification.

My invention relates to can tipping ma- 1 chines such as are used in thecanning 111-. dustry for sealing the vent holes of the cans after thecaps have been soldered in place. 7 The'invention relates; particularlyto certain improvements in the construction of r the tipping machinepatented to me Aug. 6,

1912 and numbered 1,034,47 3 and the object of the invention is to makethe machine more compact and to provide means for moreaccuratclyadjustingthe parts.

The machine covered by my a line of loans,'a'tipping iron pivoted abovei the line of cans to a pivoted frame and means actuated by the passingcan for "swinging the pivoted frame to lower the tipping iron-at theright instantqto drop its point into the vent holejof the can andto liftit again after it had been carried a limited distance-by-the movement ofthe can whereby thetipping iron would swing back to its normal position.

My invention may best be understood reference to the accompanyingdrawing,

wherein isshown a tipping machine of the general character"describedwith my improved construction applied thereto.

In th drawing, Figure 1 is a side elevation ofgthe machine, Fig. 2 is arear elevation, Fig. 3 isa plan, Fig. 4 is a section on the line as m ofFig. 3, Fig. 5 is a front elevation of the-pivot for suspending thetipping implement and its support. Fig. 6 is a vertical section throughthe "same, and Fig. 7 isa detail of the guidefor centering the tippingimplement.

In the drawing dicate' like parts. 1

The tipping machine is usually applied to a conveyer having amovable'bed consisting of a series of lags 1 traveling on'stringe likereference figures in- ;ers 2 and: connected together by a sprocket 50.

movable frame which is raised and supported by aspring and depressed bya lever actuated by the side of the passing can.

-As here shown, the frame consists of a .rod 5 adaptedto slidevertically in guides 6 and 7 positioned one above the other. The rod 5is prevented from turning and is held steadily'in positionby a guide rod10 parallel with the rod 5 and connected 7 with it atthe upper end by across head 9. The lower end of the rod 10 passes through a guide 10K anda helical springfll surrounds the rod and provides the means forsustaining and lifting the entire frame in- ;cluding the tipping iron.The lower end of thespring 11 lmpinges on the guide 10' and theupper endrests against an adjusting nut former patent included a feedingmechanism for feeding 20.

12 threaded on the rod. By screwing the nut up or down the tensionof'the spring may be regulated and the lifting power of the frame nicelyadjusted.

lTh. tipping iron 8 is suspended by its stem from the pivot 13 and thelatter is carried by a horizontally adjustable rod 1 1 fittingin thecrosshead 9, the rod being held in place by a setscrew 15'. The pivot isso secured to the end of the rodas to be verticallyad ustable. As hereinshown a verticatguide 18 is secured to the end of the ,rod 14 and inthis guide is a pivot block 16 carrying the pivot 13 to which thetipping implement is hung.

A screw 17 journaled in the guide 18 engages the block 16 andprovidesthe means for its vertical adjustment and a vertical rod -17secured to the guide 18 parallel with the'screw 17 passes through theinnerportion of the pivot block and serves to guide the same. g

The adjustment of the tipping iron in the direction of the feed of thecans is secured by a V-shaped guide 19 adjustably secured to the end ofa bracket 20' projecting out from the body of the machine. This guidereceives and centers the stem of the tipping iron as it swings backafter tipping the can and" its position determines the position of thetipping iron and enables it to be so adjusted that it will enter thevent hole when the frame is depressed. The frame and the tipping ironare depressed by the force exerted by the passing can.

i As here shown the rod 5 is depressed by a centrally pivoted lever 21,one end of which engages a pin 22 set in a slot in the lower end of therod. The opposite end of the frame 38 and pressed inwardly against the.

lever carries an antifriction roll 23 which bears normally against abearing surface 24 formed on the pivoted arm 26. The arm 26 carries onits free end an antifrlction roll 27 which is designed to contact withthe side of each can as it passes-by and to be forced outwardly thereby.As the arm 26 swings outwardly, the lever 21 is moved on its pivot pointand its outer end depresses the rod 5. r The upper portion of the roll27 is formed into an upwardly flaring flange which fits over the uppercorner of the can and tends to hold it from tilting on its travelingbed.

The arm 26 is prevented from swinging too far inward when not in contactwith a can by means of a hook 34 secured to the 1 arm 26 and extendingoutward to engage the rod 28 which forms the pivot for the lever 21. l

Lateral guides 29 are provided to hold the cans in line while they arepassing the tipping mechanism and a double upper guide plate 30 islocated so that the cans pass immediately beneath it, the cans. beingthereby prevented from tilting and getting out of position. The guideplate 30 is.

secured to the lower end of a guide rod 32 and the latter is adjustablysecured in a bracket 31 fastened to the frame of the ma-. chine. The canis given a rotating move ment as it passes the tipping mechanism bymeans of a horizontally disposed rubber tired roller 33 journaled in aswinging side of the passing can by a spring 35.

. Rotation is given to the roll 33 by a pulley 36 which isfitted to apulley not here shown andfrom which power is derived. From what has beensaid the. operation of my improved machine may be readily understood. Asthe cans pass by, each can comes in contact with the roll 27 on the arm26 and'forcing it outward depresses the end of the-lever 21 and theframe'to which the tipping iron is hung. The point of the iron entersthe'vent hole and, as the can moves along, it carries the tipping ironalong with it far enough to seal the vent hole. The can is rotated bythe roll 33 during thisopera-tio'n insuring the even distribution of thesolder in the vent hole. 7 When the canhas passed by, the arm 26 isreleased and the rod 5 and its connecting parts carrying the tippingiron are lifted and the iron swings back to a bearing in'the forkedguide 19 where it remains until the next can comes along.

-The mechanism for feeding solder to the tipping iron which is no partof my present invention is not shown herein.

A tipping machine constructed as above described is simple and compact.It con tains all the adjustments necessary to accurately place thetipping iron so that its point will always strike in the vent hole.
